secure-wire for aggregated interface member links documented design is not working

Hello collegues,

I'm testing secure-wire on srx in junos 12.3x48 using guide

http://www.juniper.net/techpubs/en_US/junos12.3x48/topics/example/layer-2-secure-wire-for-aggrgated-interface-member-link-configuring.html

But it seems that this design is not usable. For example if port ge-0/0/0 goes down and traffic enters port ge-0/0/1 it will be dropped.

 So could somebody suggest how authors of that guide planned to recovery from faults on interfaces?

Thanks in advance for any ideas!
